Olof Johansson f0390669d1 ARM: tegra: cleanup
This pull request contains various cleanup and minor changes to core
 Tegra code:
 * Tegra clocksource driver is moved to drivers/clocksource.
 * Various typos, warning cleanup, statics cleanup, section mismatch
   fixes, etc.
 * Various small fixes/cleanups for CPU/hotplug/SMP code.
 
 This pull request is based on a merge of v3.8-rc3 and at least part of
 arm-soc's timer/cleanup branch.
